Daisy Bell was written by Harry Dacre in 1892 and became famous again when an IBM computer sang it in 1961, the first time a computer performed a song. It later became widely known through HAL 9000 singing it in the 1968 film 2001: A Space Odyssey. Slowed and distorted versions have since circulated online as creepy meme audio, and this version is shared for Gorilla Tag, where players and editors use its haunted, old-fashioned tune to make VR gameplay feel stranger and more unsettling.
